AND PROPERTY DAMAGE. READ AND UNDERSTAND ALL WARNINGS AND OPERATING INSTRUC-
TIONS BEFORE USING.
HAZARD
• Unsafe operation of your pressure washer
could lead to serious injury or death to you or
others.
• If proper starting procedure is not fol-
lowed, engine can kickback causing serious hand and arm injury.
• The spray gun/wand is a powerful cleaning
tool that could look like a toy to a child.
• Reactive force of spray will cause gun/wand
to move, and could cause the operator to slip
or fall, or misdirect the spray. Improper control
of gun/wand can result in injuries to self and
others.
• Become familiar with the operation and controls of the pressure washer.
• Keep operating area clear of all persons,
pets, and obstacles.

• Never defeat the safety features of this product.
• Do not operate machine with missing, broken, or unauthorized parts.
• Never leave wand unattended while unit is
running.
• If engine does not start after two pulls,
squeeze trigger of gun to relieve pump
pressure. Pull starter cord slowly until
resistance is felt. Then pull cord rapidly to
avoid kickback and prevent hand or arm
injury.
• Keep children away from the pressure washer at all times.
• Do not overreach or stand on an unstable
support. Grip gun/wand firmly with both
hands. Expect the gun to kick when triggered.
HOW TO PREVENT ITWHAT CAN HAPPEN
RISK TO BREATHING
RISK OF EXPLOSION
OR FIRE
RISK OF UNSAFE
OPERATION
• Shut off engine and allow it to cool before
adding fuel to the tank.
• Use care in filling tank to avoid spilling fuel.
Move pressure washer away from fueling
area before starting engine.
• Keep maximum fuel level ½” below top of
tank to allow for expansion.
• Operate and fuel equipment in well ventilated
areas free from obstructions. Equip areas
with fire extinguishers suitable for gasoline
fires.
• Never operate pressure washer in an area
containing dry brush or weeds.
• Always keep pressure washer a minimum of
four feet away from surfaces (such as houses, automobiles, or live plants) that could be
damaged from muffler exhaust heat.
• Store fuel in an OSHA approved container, in
a secure location away from work area.
• Do not spray flammable liquids
• Spilled gasoline and it’s vapors can become
ignited from cigarette sparks, electrical arcing,
exhaust gases, and hot engine components
such as the muffler.
• Heat will expand fuel in the tank which could
result in spillage and possible fire explosion.
• Operating the pressure washer in an explosive
environment could result in a fire.
• Materials placed against or near the pressure
washer can interfere with its proper ventilation
features causing overheating and possible ignition of the materials.
• Muffler exhaust heat can damage painted surfaces, melt any material sensitive to heat (such
as siding, plastic, rubber, or vinyl), and damage
live plants.
• Improperly stored fuel could lead to accidental
ignition. Fuel improperly secured could
get into the hands of children or other unqualified persons.
• Use of acids, toxic or corrosive chemicals, poisons, insecticides, or any kind of flammable
solvent with this product could result in serious
injury or death.
• Breathing exhaust fumes will cause serious
injury or death.
• Some cleaning fluids contain substances which
could cause injury to skin, eyes, or lungs.
• Operate pressure washer in a well ventilated
area. Avoid enclosed areas such as garages,
basements ,etc.
• Never operate unit in a location occupied by
humans or animals.
• Use only cleaning fluids specifically recommended for high pressure washers. Follow
manufacturers recommendations.Do not use
chlorine bleach or any other corrosive compound
IMPORTANT SAFETY INSTRUCTIONS
4 — ENG
HAZARD
• Fuel or oil can leak or spill and could
result in fire or breathing hazard, serious
injury or death can result. Fuel or oil leaks
will damage carpet, paint or other surfaces in vehicles or trailers.
• If pressure washer is equipped with a fuel
shut-off valve, turn the valve to the off position
before transporting to avoid fuel leaks. If pressure washer is not equipped with a fuel shutoff valve, drain the fuel from tank before transporting. Only transport fuel in an OSHA
approved container. Always place pressure
washer on a protective mat when transporting
to protect against damage to vehicle from
leaks. Remove pressure washer from vehicle
immediately upon arrival at your destination.
WHAT CAN HAPPEN HOW TO PREVENT IT
RISK OF
ELECTRICAL
SHOCK
RISK OF CHEMICAL BURN
RISK OF HOT SURFACES
RISK TO FLUID
INJECTION
The powerful spray from your pressure washer is capable of causing damage to surfaces such as
wood, glass, automobile paint, auto striping and trim, and delicate objects such as flowers and
shrubs. Before spraying, check the item to be cleaned to assure yourself that it is strong enough to resist damage from
the force of the spray. Avoid the use of the concentrated spray stream except for very strong surfaces like concrete and
steel.
Operating without flow of water will result in equipment damage. Operating the pressure washer with water supply
shutoff will void your warranty. You should never run this pressure washer for more than 2 minutes without pulling the
trigger to allow cool water to enter the pump and the heated (recirculated) water to exit.
RISK OF INJURY AND
PROPERTY DAMAGE
WHEN TRANSPORTING OR
STORING
• Spray directed at electrical outlets or
switches, or objects connected to an electrical circuit, could result in a fatal electrical shock.
• Unplug any electrically operated product
before attempting to clean it. Direct spray
away from electric outlets and switches.
• Your washer operates at fluid pressures
and velocities high enough to penetrate
human and animal flesh, which could
result in amputation or other serious
injury. Leaks caused by loose fittings or
worn or damaged hoses can result in injection injuries. DO NOT TREAT FLUID INJECTION AS A SIMPLE CUT! See a physician immediately!
• Relieve system pressure before attempting
maintenance or disassembly of equipment.
• Never place hands in front of nozzle.
• Direct spray away from self and others.
• Make sure hose and fittings are tightened
and in good condition. Never hold onto the
hose or fittings during operation.
• Do not allow hose to contact muffler.
• Never attach or remove wand or hose fittings
while system is pressurized.
• Use only hose and high pressure accessories
rated for pressure higher than your pressure
washer's p.s.i.
• To relieve system pressure, shut off engine,
turn off water supply, and pull gun trigger until
water stops flowing.
• Use of acids, toxic or corrosive chemicals,
poisons, insecticides, or any kind of flammable solvent with this product could result in serious injury or death.
• Do not use acids, gasoline, kerosene, or any
other flammable materials in this product.
Use only household detergents,
cleaners and degreasers recommended for
use in pressure washers.
• Wear protective clothing to protect eyes and
skin from contact with sprayed materials.
• Do not use chlorine bleach or any other corrosive compound.
• Contact with hot surfaces, such as engines
exhaust components, could result in serious burn.
• During operation, touch only the control surfaces of the pressure washer. Keep children
away from the pressure washer at all times.
